TEX

Tex is a fully automatic all-hexahedral meshing software particularly suited for the non-linear analysis of complex shapes with wide scale disparities such as light aerostructures, electronic components, MEMS, fluidic devices, complex manufacturing processes and shapes with locally high aspect-ratios such as parts commonplace in additive manufacturing and automated shape optimization.

Tex uses Mid-object Extraction and Extrusion at Saddle points (MEES) ( 1 ) to decompose complex geometries into compatible extrudable blocks where mesh resolution spanwise and across the object are independent. The result is a quality all-hexahedral mesh with element counts well below other meshing techniques. In fact, often, for the same analysis accuracy, Tex meshes have 10 to 100 times fewer elements than equivalent tetrahedral meshes, and their analyses converge faster.

Tex is only available through SIW. For further information please complete the Contact Form in the About section.

Features of tex

• Produces a block-structured hexahedral mesh.

• Well-suited for the non-linear analysis of 3D objects featuring thin regions.

• Option to produce all-hexahedral or mixed hex/prism/tetra elements.

• Ability to control independently mesh density spanwise and across thin parts.

• Compatible with most PLM and FEA systems.

• Requires only a closed triangulated surface and as few as one user parameter.

• Available as an X64 executable.

Benefits of tex

• Extremely easy to use: all examples shown were created using default parameters

• High-quality meshes that yield more accurate results faster and cheaper.

• Ideal for both linear and non-linear (plasticity, failure, CFD, etc.) analyses.

• Robust and symmetry-conserving.

• Element layering is intuitive and conformal to object boundaries.

• Can be easily integrated into existing CAE and CAD systems.
